ARCS WIDE    Constant Curvature WST Line So


The ARCS® WIDE  systems are based on two constant curvature enclosures ensuring distinct directivity pattern and SPL capabilities. Intended for medium-throw applications in rental productions and fixed installations, these line sources deliver remarkable acoustic properties and unmatched versatility for applications including FOH L/R systems, central clusters, side-fill monitors, distributed systems and complementary fills. The main system components are as follows:

• ARCS WIDE (H x V: 30° x 90°) full-range element, wide coverage, operating from 55 Hz to 20 kHz

• LA4X or LA8 amplified controllers The ARCS WIDE or ARCS FOCUS line sources provide high SPL with perfect acoustic coupling, a solid LF performance and constant tonal balance over distance. Both systems can be deployed either as a horizontal array or as a vertical array. In the coupling plane, the ARCS WIDE and ARCS FOCUS yield a razor-sharp directivity pattern, particularly valuable to sector audience fields while avoiding reflective surfaces. In the other plane, both systems provide a 90° smooth symmetric directivity pattern.

The ARCS WIDE is suited to achieve an extensive coverage with few elements, offering a remarkably compact array preserving sightlines.

The total coverage angle of an ARCS WIDE line source is proportional to the number N of enclosures in the array, i.e. N x 30°. The ARCS FOCUS line source focuses the same acoustic energy within half of the coverage angle, i.e. N x 15°. The ARCS FOCUS is therefore suited to achieve a narrower coverage, offering a higher SPL with a more extended throw than its sibling. The

ARCS WIDE and ARCS FOCUS can also be deployed in “WIFO” hybrid arrays for complex audience geometries. The dual directivity pattern and the various system configurations offered to the sound designer and system engineer allow a high level of creative freedom. Before installation, all these configurations can be acoustically and mechanically modeled with the SOUNDVISION 3D simulation software.

The LA4X and LA8 amplified controllers are the heart of the system. Both enclosures can be precisely driven with the same factory preset. All L-ACOUSTICS amplified controllers feature the L-DRIVE, a thermal and over-excursion protection circuit.

Up to 253 LA8 amplified controllers can be connected together via the Ethernet-based L-NET protocol. The LA NETWORK MANAGER software allows online remote control and monitoring of all the connected units, via a user-friendly and intuitive graphic interface, and features the Array Morphing EQ. This exclusive tool allows the engineer to quickly adjust the tonal balance of the system to reach a reference curve or to ensure consistency of the sonic signature.
